Wonder Cave

Wonder Cave (Kromdraai, Gauteng)

The Wonder Cave, in Kromdraai, Gauteng, South Africa, is the third-largest cave chamber in the country, and is believed to be about 1.5 million years old. The single chamber has an area of 46000 square metres, and is 125 metres long and 154 metres wide.

It was discovered in the late 19th century by miners who dynamited and excavated limestone for the making of cement. Mining stopped during the Second Boer War, and never resumed.
